I have been working on this project for over a year now and I am pleased enough with the result to upload it.
The goal was to make a modern looking bird feeder that is simple to set up and has a refilling procedure.
What annoys me is that since it is supposed to be hung on a tree, it rotates and swings from time to time.
Luckily, the birds don't seem to care too much. 3 of the bird feeders were hung in different locations and 2 of them are getting used a lot. The other one not so much. Keep in mind that the content of the food in the feeders as well as the location it is hung has a huge impact on how much birds accept it.
Both the "High Capacity" and "Low Capacity Lower" need support to be printed.
6mm diameter rods ideally made of wood.
You can put some hot glue around the rope where it goes through the roof to water seal it. Just make sure it can still be lifted.
